DEMOUNTABLE RIM.

To all 'w 710m it may concern:

Be it known that I7 Cenni. A. PARKER, a citizen ot the United States, residing at Cleveland, in the county ot Cuyahoga and State ot Chio, have invented a certain new and usetul Improvement in Demountable Rims, ot which the tolloiving is a tull, clear, and exact description, reference being had to the accompanying drawings.

rI`his invention relates generally to demountable rims and more particularly to means tor securing the demountable tire carrying rim to the Wheel body. Various devices have been employed tor securing the demountable tire carrying rims upon Wheels but all or nearly all, ot these devices have required a number ot separated parts which called tor considerable care and skill in their manipulation in order to tasten the rim upon the Wheel in a true plane and properly centered.

lith the idea ot dispensing with a large number ot these parts and consequently eliminating many ot the operations I have devised the present rim tastening means, and generally speaking the invention consists in certain details ot construction and novelties ot arrangement all ot which Will be tully described hereinafter and pointed out in the claims.

In the drawings torming part ot this specification Figure 1 is a tace view ot a Wheel embodying my invention; Fig. 2 is a sectional view taken on the line Qf-Q ot Fig. l; Fig. 3 is a section on the line 3 3 ot Fig. l; and Fig. l is a tace 'view showing a slight modification.

In the practical embodiment ot my invention I employ a Wheel A one halt ot Which is concentric and the other halt eccentric, this halt ot the vvheel being rendered ece centric by removing a very small portion ot the Wooden telly as indicated at A. It desired lthe vvheel can be made eccentric with certain negligible inaccuracies by placing the hub bore slightly to one side ot the true center ot the Wheel. Upon this eccentric Wheel is tastened the metal telly band B having the inclined flange B at the inner edge thcreot, upon the eccentric portion only ot the Wheel or a part ot said eccentric portion. The tire carrying rim C is as near a true circle as such rims are made commercially and is adapted to tit upon the Wheel body; one halt ot the rim fitting upon the concentric portion ot said Wheeli Specification of Letters Patent.

body While the other halt ot the rim drops treely about the eccentric portion ot the Wheel body and comes in contact with the liange B at the inner edge ot the telly band, and 1n order to tension the rim upon the Wheel body I provide lateral clamps I) arranged upon the ends ot bolts E passing through the eccentric portion ot the Wheel telly and these clamps bind against the outer flange ot the rim and torce the opposite edge ot the rim into contact with the inclined tlange B thereby drawing the other halt ot the rim firmly into contact with the concentric portion ot the telly band and tensloning the rim as a whole and securing it iirmly upon the Wheel body. The Wheel body is made eccentric only tor the purpose ot enabling the rim to be quickly rocked or buttoned or svvung thereon or removed theretrom and consequently the three lateral clamps acting upon the rim Will be suiiicient to tension the entire rim and irmly bind the rim upon the concentric portion ot the Wheel body and securely Wedge the other portion ot the rim against the flange ot the telly band upon the eccentric portion ot the vvheel.

. A doivel F is attached to the rim and tits into a suitable elongated recess B2 made in the telly band and a second doivel or driving lug F tubular in torm, is attached to the rim and spaced about 90 theretrom and through Which the valve stem ot the tire is adapted to pass, this driving lug serving the double tunction ot a guide toi` the valve stem and positioning the rim upon the Wheel body in all directions: and by placing the dowels or lugs F and F a corisiderable distance apart, as indicated, lateral supports will be provided tor the concentric portion ot the rim at Widely spaced points, which, in connection With the three lateral clamps, will be tound amply sufficient to securely tasten the rim upon the Wheel. In Fig. Ll, I have shown a slight modilication in which the upper halt ot the Wheel body is provided With blocks or strips B3 tor the purpose ot making a portion ot the Wheel eccentric with reterence to the rest, the lower halt ot the Wheel being devoid ot such spacing blocks or strips. In this construction one halt ot the rim Will rest upon the spacing blocks or strips, While the other halt will tall treely over the telly band devoid ot such blocks and strips. and when the clamps are applied and the rim tensioned the upper half of said rim will be drawn down firmly upon the blocks or strips exactly the same as previously described. A dowel or dowels near the valve stem, and approximately at the center of the concen tric portion of the Wheel, in connection with the lateral clamps upon the opposite side of the wheel Will be sufficient to properly secure the rim upon the Wheel body.

In operation, the valve stem and dowels are brought into engagement with their recesses thereby positioning the. concentric portion of the Wheel. The rim 1s then dropped around the eccentric portion of the wheel body and 'contacts with the flange at the back and then by tightening up the lateral clamps the rim Will be securely fastened upon the Wheel in a true plane and properly centered.

The removal of the rim can be quickly and easily accom lished by simply unfastening the lateral c amps, turning them out of engagement with the rim and pulling the rim ofi' as usual.

It will thus be seen that I properly and securely fasten a demountable tire carry-l in rim upon a Wheel body by the use of a minimum number of fastening elements, and

at thc saine time avoid the common erroi of mounting a rim off center and out of its true plane.

It is obvious that the blocks referred to in Fig. 4 may be attached to the rim instead of to the felly band, Without in any Way changing the results obtained.

Having thus described my invention, what I claim is 1. The combination with a wheel body, a portion of which is concentric and the remaining portion eccentric, of a felly band afliXed thereto and having an inclined flange at the back, a demountable tire carrying rim adapted to fit upon said felly band, and rim fastening means attached to the eccentric portion of the wheel body and contacting with that portion of the rim contiguous to the eccentric portion ofthe Wheel body.

2. The combination with a wheel body,

a portion of which is concentric and the remaining portion eccentric, of a felly band affixed thereto and having an inclined flange at its back, a demountable tire carrying rim and clamps attached to the eccentric portion of the Wheel body and bearing against the side portion of the rim contiguous to said eccentric portion of the wheel body whereby a portion of the rim is drawn down on the concentric portion of the felly band and the remaining portion is tensioned against the inclined flange.

3. The combination with a Wheel body, one portion of which is eccentric, of a felly band affixed to said wheel body, the eccentric portion of the felly band having an inclined flange at its back, a demountable tire carrying rim adapted to t upon said Wheel body, and lateral clamping means carried by the eccentric portion of the Wheel body 'and adapted to contact with the contiguous portion of said rim to bind the same against the inclined flange.

4. The combination with a Wheel body, va portion of which is eccentric, a felly band affixed thereto, the eccentric portion of said felly band having an inclined flange at its back, a demountable tire carrying rims having dowels spaced at considerable distance and adapted to engage the concentric portion of the Wheel body and lateral clamps carried by the eccentric portion of said Wheel body, adapted to contact Awith the contiguous portion of said rim to bind same against inclined flange.

5. The combination with a wheel body, a portion of which is concentric and the remaining portion eccentric and having an inclined flange at the back, of a demountable tire carrying rim, and clamps attached to the eccentric portion of wheel body and bearing against the contiguous portions of the tire carrying rim to bind the saine against the inclined flange at the back of said portion.

In testimony whereof I hereunto affix my signature.
